COMPOSITE ROLL FOR TEXTILES.

' Specification of Letters Patent.

Patented Jan. 11, 1916.

Application filed September 10, 1914. Serial No. 861,035.

To all whom it may concern Be it known that I, WILLIAM F. GAM- METER, citizen of the United States, residing at Cadiz, inthe county of Harrison and State of Ohio, have invente d certain new and useful Improvements in Composite Rolls for Textiles, of which the following is a specification.

My invention relates to new and useful improvements in composite rolls for use in winding textiles and fabrics, the primary object of my inventionbeing the provision of a roll having a built up body of wood or other suitable material, the parts of Which are glued or otherwise fastened together, the body being reinforced at its ends by suitable metalcaps or ferrules.

A further object of my invention is to provide a roll of the above described character. having a centrally formed, squared bore adapted to receive the squared mandrel upon whichthe roll is used, the caps or ferrules tail pieces which form continuations of the bores to reinforce the roll and to provide for the distribution of rotary strain to all parts of the roll.

A still further ob]'ect'of my invention is to provide both the inner and outer flanges of the caps with beveled roll engaging faces in such a manner that the ferrules or caps upon thebody of the roll by a press or other means, of the roll to prevent them from sp'lintering and to protect the wood from wear.

\Vith these and other objects in view, my

invention will be more fully described, illustrated in.the accompanying drawing, and then specifically pointed out in the claims which are attached to and form a part of this application. V

In-the drawing: Figure 1 is a perspective view of my improved roll; Fig. 2 is a central longitudinal sectional view taken through a plane parallel to the plane of one of the faces of the squared bore; Fig. 3 is a transverse sectional view, taken on the line 3-3 of Fig. 2, the roll body, in partially finished condition, being shown in dot and dash lines in this figure; Fig. 4 is an end view of the roll body in finished condition but before the application of the cap or ferrule; Fig. 5 is a perspective view of the cap or ferrule employed upon my rolls, looking at it from its inner face.

Corresponding and lilge parts are referred being provided with inner flanges or" will bindv the ends to in the following description and indicated in all the views of the drawing by the same reference characters.

Broadly speaking, my improved compositeroll includes a body portion 10 provided at its ends with caps or ferrulesll of metal or other suitable material, the body and caps being so constructed as to form a central longitudinally extending, squared bore.

More specifically, as will be seen best by referring to Fig. 3 ,of the drawings, the body portion of the roll is constructed from a number of separate pieces of Wood,,indicated by the letters a, b, 0 and d. Each of these pieces of wood is in the form of a strip equal in length to the length of the roll and substantially rectangular in cross section. Further, the strips a, and b are equal in width to the diameter of the roll, while the strips 6 are of less width and of such thickness that either one, together with the strips a and b,

will be equal in thickness to the diameter of jacent the longitudinal edges thereof, as

shown in Fig. 3, the inner faces of the strips a and. b will bear snugly andsmoothly against the adjacent faces of the strips 0 and d, while portions of the inner faces of the strips a andv I), together with the inner faces of the strips 0 and (Z, will form a perfectly uniform, smooth and uninterrupted squared bore disposed centrally of the body portion which, as now formed, is substantially square in cross section. The portions or strips a, b, c and (Z are firmly glued or otherwise secured together in this position, after which the body portion, thus roughly formed, is placed upon a suitable machine and turned to cylindrical form.

The end portions of the roll body are then cutaway circumferentially, asshown at 12, in Fig. 2, to provide slightly tapered terminals and resultant ann'ula'r stop shoulders 13. Said end portions are further cut-away I outwardly, as shown, and such cut-away por I tions providing stop, shoulders 16. Itwill of course be clear that this cutting away of the interior portions of the body of the roll may be accomplished before the rough forming of the rollby properly cutting the strips from which the roll is. formed, if such method be foundmore advantageous either because of simplicity in operation or becausemore accurate cutting is possible.

-When the roll has been thus formed, the caps or ferrules 11 are forced upon its'ends by means of a press or other suitable mechanism to firmly bind the ends of the roll forming strips to prevent their splintering and. to protect them fromwear during use. Each of these caps orferrules, both being identical in construction, includes a circular body portion 17 provided centrally with a squared opening 18. equal in size to the squared bore of the body portion of the roll, and further provided with a laterally directed peripheral flange 19 and an interiorly formed, laterally directed, flange 2O surrounding the squared opening 18,-both flanges extending from the .same face of the body portion of the cap or ferrule. Asmost clearly shown in Fig. 2 of the drawings,-the flange 419 is thickened interiorly adjacent the body portionof the cap, tapering from its inner to its outer part to provide an inclined face "corresponding to J .the inclined terminals of the roll,,while the able distance into the roll to flange 20 is similarly thickened exterior-1y to correspondto the inclined faces formed by cutting away the end portions of the roll about the squared bore 15. Preferably,

however, the space between theflanges l9 and 20 is somewhat slighter than the space between inner and outer corresponding por'- tions of the ends'of the roll body in order that th e said end portions of the roll body shall becompressed between these flanges when the cap or ferrule is forced into place.

It should also be noted that the flange 20 is of greater lateral'ext'ent than the flange 19., for which reason it may extend a considerproperly reinforce it. J

The above completed roll is employed in the. usual manner, being capable of use upon --a squared metal mandrel as such mandrel may be extended through the bore of the roll which shouldbe roportioned to receive it with reasonable coseness. Under these conditions, it will be apparentthat the caps or ferrules not only serve to prevent the ends of the roll from splintering, but also to prevent injury to the roll, due to rotary strain applied to it by turning movement of the mandrel. In addition to this, the flanges 20 "of the ferrules take up the greater portion of the strain applied to the rollby the mandrel, and as the ends2 of the roll are compressed between such flange and the flange 19, distribute such strain equally to all parts locking shoulders and ribs materially assist -in holding the roll forming strips or sec- 1 my invention.

of the roll, thus permitting the placih'g of a much heavier load upon the roll, without danger of its falling apart, than would otherwise be possible.

Although not absolutely essential, I preferably provide means for securing the caps or ferrules against displacement from the roll ends but do not wish" in anyway to limit myself to any specific means for this purpose. One manner of accomplishing this consists in the employment of splitrivets 21 which may be driven through openings formed in the caps or ferrules and into the wood of the roll body, the rivets being-so formed that when driven intothe wood their legs will separate and turn to form hooks to prevent their withdrawal.

Preferably, the stripsa and b are provided in their inner faces, and slightlyspaced from those portions of such faces which form the walls of the bore, with longitudinal channels 22 to seat longitudinal ribs or shoulders 23 formed upon the opposite side walls of the strips '0 and 03. These intertions together, particularly during the shaping of the roll which, of necessity, must be done before application of the caps or ferrules. I

Although I have illustrated and described my invention in all its details, it will of course be understood that. I doano t wish to -limit myself to the specific detailsof con struction, illustrated and described, as various changes, within the scope ofthe ppended claims, may be made, without in the and peripheral flanges extending-laterally from the caps and surrounding the eXteri-or end portions of the body, said end portions beingcut-awa y to seat these latter flanges, and the outer surface of said flanges being flush with the surface of the body.

2. A roll including a cylindrical built up v v body having a squared-longitudinal bore of I uniform size throughout its length, the walls of said bore being flared at their ends and the body being tapered eXternall at its ends, and protective caps secured to the body portion engaging against the end of the roll body, an outer circular flange havends of the body, said caps each including a end of-the bore,

'ing an inclined inner face fitting on the tapered end of .the'roll. body,' and aninne'r squared flange oi-Sleeve projecting into thethe outer'face of said inner flange being-inclined t-o fit'the flared end of the bore-of the roll body and the inner face of the said flange being flush with, the Walls of the bore, the body of the cap being formed with a squared opening forming a body and equal in size thereto.

In testlmony whereof I aflix my signaturev inpresence of two itnesses.
